NGC 281 is an 80 light-year diameter dust cloud some 10,000 light years away in the constellation of Cassiopeia. The nebula was discovered by EE Barnard in August 1883.
Contained within the cloud is the open cluster IC 1590.
NGC 281 contains a number of dark globules within which (it is believed) new stars are forming. These are named Bok Globules after the Dutch-American astronomer – Bart Bok who first described these in the 1940s.
The Pacman Nebula was photographed between 30 September and 24 October 2019 from a remote imaging rig that is jointly owned and operated by Barry Wilson and me.
